your parents invest $500 on each birthday since the day you were born until you're 25. each investment earns 6.4% simple interest.

how much will you have on your 25th birthday?

2 answers

If you are talking about simple interest and not compounding interest then you would just use the formula:

A = P+ Prt

Where Prt is the interest.

500 x 25 = 12500

A = 12500 + 500(.064)(25)
